In how many ways can the letters
in the word glacier be arranged?

5,040 times

Step-by-step explanation:

Since there are 7 letters in the word glacier, and there is no set limit, the formula would look like this;

7x6x5x4x3x2x1

(and techinacally 0 counts as 1, but since any number x 1 is itself, it's unnecessary to put it in there)

All of this adds up to 5,040

(I also have acellus and I've already checked it and it's correct )

Step-by-step explanation:

area of a circle =πr²

where r=radius and π=pi

circumference=2πr

or πd

where d= diameter
